That, GPS receiver 4 ₁ is provided on or near the AP3 ₁ housing, supplies the position information indicating the installation position of the AP3 ₁ to AP3 _1. Further, GPS receiver 4 ₂ is disposed on or near the AP3 ₂ of the housing, it supplies the position information indicating the installation position of the AP3 ₂ to AP3 _2. Further, GPS receiver 4 ₃ is provided on or near the AP3 ₃ of the housing, supplies the position information indicating the installation position of the AP3 ₃ to AP3 _3.

  The SIP terminal 5 as a wireless communication terminal is assigned a telephone number or address for receiving a two-way communication service using a subscriber line, such as a mobile phone (including a smartphone) or a tablet computer. And a wireless communication terminal having an audio output function.

Below, the communication operation | movement performed in the above-mentioned communication system 10 is demonstrated along the communication flow shown in FIG. Incidentally, such a communication operation is for the user to carry the SIP terminal 5 is made when entering into the wireless communication area CA _1.

First, the SIP terminal 5 located AP3 ₁ of the wireless communication area CA _1, as shown in FIG. 4, the transmission destination (the To), the sender (the From) and communication identification number [Call-ID] information shown respectively A REGISTER request signal RM1 having a header including “” is wirelessly transmitted to AP3 ₁ (step S1). That is, the SIP terminal 5 transmits a REGISTER request signal as a terminal registration request signal in order to register the SIP terminal 5 in the SIP server 1.

When receiving the REGISTER request signal RM1, the AP3 ₁ transmits a REGISTER request signal RM2 having a header in which the location information XP indicating the installation position of the AP3 ₁ is added to the header of the REGISTER request signal RM1 as shown in FIG. The data is transmitted to the SIP server 1 via the line network 2 (step S2).

When receiving the REGISTER request signal RM2, the SIP server 1 performs communication registration processing (not described) based on various information indicated by the REGISTER request signal RM2. At this time, when the communication registration process is completed, the SIP server 1 transmits a [200 OK] code indicating that the communication registration process corresponding to the REGISTER request has been normally performed, to the SIP of the transmission source of the REGISTER request signal RM1. In order to notify the terminal 5, this is transmitted to the AP 3 ₁ (step S3). When the [200 OK] code is received, the AP3 ₁ wirelessly relays the [200 OK] code to the SIP terminal 5 that is the transmission source of the REGISTER request signal RM1 (step S4).

Further, after the end of step S3, the SIP server 1 extracts the position information XP from the header of the REGISTER request signal RM2 as shown in FIG. 5, and is associated with the installation position of the AP 3 ₁ indicated by the position information XP. The peripheral information is read out from the peripheral information memory having the stored contents as shown in FIG. 2B (step S5). Then, SIP server 1, the character data indicating such Things as the short message to be sent to the sender of the SIP terminal 5 of the REGISTER request signals RM1, transmits the short message to AP3 ₁ (step S6). That is, the SIP server 1 sets the destination telephone number corresponding to the registered address (SIP URI) included in the REGISTER request signal RM2 received as described above as the telephone number of the stored contents as shown in FIG. It reads from the memory and sends a short message with the phone number as the destination. Note that when the destination telephone number is included in the header of the REGISTER request signal RM2, the SIP server 1 may transmit a short message using the telephone number as the destination.

Upon receipt of the short message, AP3 ₁ is the short message, the terminal to send the phone number as described above, that is wirelessly relayed to the sender of the SIP terminal 5 of the REGISTER request signal RM1 (step S7).

When receiving the short message, the SIP terminal 5 displays the character information represented by the short message on the screen (step S8). For example, in the above embodiment, since the SIP terminal 5 exists in AP3 ₁ of the wireless communication area CA _1, the execution of step S8 described above, the peripheral information corresponding to the installation position of such AP3 ₁ shown in FIG. 2 6 is displayed on the screen of the SIP terminal 5 as shown in FIG.

Therefore, according to the communication system 10, the user who carries the SIP terminal 5 entering a wireless communication area of the wireless access point _{(3 1 ~3 3) (CA} 1 ~CA 3), the wireless access point Information (facility name, facility content, implementation event, URL, etc.) related to the facility around the installation position is automatically displayed on the screen of the SIP terminal 5. Therefore, the user of the SIP terminal 5 can immediately obtain information on the facility existing in the vicinity of the current location without performing a search operation by the SIP terminal 5.

In the above embodiment, when the SIP terminal 5 enters the radio communication area of the wireless access point _{(3 1 ~3 3) (CA} 1 ~CA 3), the wireless access point, the own position Although the position information XP indicated is transmitted to the SIP server 1, the position information indicating the current position of the SIP terminal 5 may be transmitted to the SIP server 1. That is, the SIP terminal 5 on which the GPS receiver is mounted can appropriately acquire its own location. Therefore, in step S1, the SIP terminal 5 has a REGISTER having a header including location information XP indicating its current location, together with the transmission destination (To), transmission source (From), and communication identification number [Call-ID]. The request signal RM1 may be wirelessly transmitted to the AP3. Here, when the REGISTER request signal RM1 is received, the AP 3 determines whether or not the location information XP is included in the header of the REGISTER request signal RM1 in step S2, and if it is included, RM1. Is used as a REGISTER request signal RM2 and is transmitted to the SIP server 1 via the communication network 2. On the other hand, when the position information XP is not included in the header of the REGISTER request signal RM1, the AP 3 uses the position information detected by the GPS receiver 4 as the position information XP, and this is added to the header portion of the REGISTER request signal RM1. The added one is transmitted to the SIP server 1 as a REGISTER request signal RM2. Here, the SIP server 1 determines that the position information XP included in the header of the received REGISTER request signal RM2 does not correspond to any of the installation positions of AP3 _{1 to} AP3 ₃ as shown in FIG. When the current position of the SIP terminal 5 is indicated, the installation position of the AP 3 closest to the current position is selected. Then, the SIP server 1 reads the peripheral information associated with the selected installation position from the peripheral information memory having the stored contents as shown in FIG. 2B, and uses the character data indicating the peripheral information as a short message. The REGISTER request signal RM1 is transmitted to the SIP terminal 5 that is the transmission source.

In the above embodiment, the peripheral information, AP3 (AP3 ₁ ~AP3 ₃ each) installation position has been described as the information and the like present in the vicinity of, the vicinity of the installation position AP3 of (AP3 ₁ ~AP3 ₃ each) The area may be defined as the area of the wireless communicable area CA (CA _{1 to} CA ₃ ) determined by the installation position, and the peripheral information may be limited to the information within the area of the wireless communicable area CA.

In the above embodiment, transmission SMS function of the SIP server 1, a short message to be sent to the sender of the SIP terminal 5 of the REGISTER request signals RM1, not a component of the public line network (mobile telephone network) AP3 ₁ Then, the SIP terminal 5 receives the short message by the AP 3 ₁ wirelessly relaying the short message to the SIP terminal 5 that is the transmission source of the REGISTER request signal RM1. However, since SMS is a service that transmits text information using a public line network (mobile phone network), which is understood as part of the GSM (Global System for Mobile Communications) standard (GSM is a registered trademark). The short message may be transmitted via a public network whose function is not shown in FIG. In this case, when the SIP server 1 and the SIP terminal 5 are connected to a public line network not shown in FIG. 1 and the SIP server 1 and the SIP terminal 5 can communicate with each other, the SMS function of the SIP server 1 sets the telephone number. A short message as a transmission destination is generated, and this is wirelessly relayed to the SIP terminal 5 by a public line network not shown in FIG.

  Further, the SIP server 1 may have a line determination function for determining whether or not the SIP server 1 is connected to a public line network (mobile phone network). In this case, when the line determination function determines that the SIP server 1 is connected to the public line network (mobile phone network), the SMS function sends a short message to the public line network (mobile phone network). On the other hand, when the line determination function determines that the SIP server 1 is not connected to the public line network (mobile phone network), the SMS function sends a short message to the AP 3 as in the above embodiment.

  In the above embodiment, the SIP server 1 sends a short message exchanged over the public line network (mobile phone network) via the private network (for example, the network constituted by the communication line network 2 and / or the AP 3) to the SIP terminal. 5 has an IP-SM-GW (IP Short Message GateWay) function. Then, the IP-SM-GW function converts the short message that can be exchanged over the public line network (mobile phone network) generated by the SMS function into a short message that can be exchanged over the private network and sends it out. That is, the IP-SM-GW function converts a short message exchanged over the public line network (mobile phone network) into a SIP message and transfers it to the SIP terminal 5.

In the above-described embodiment, each of AP3 _{1 to} AP3 ₃ is a so-called autonomous wireless access point that needs to individually set various communication parameters (radio wave intensity, channel used, etc.) A so-called control type in which settings of a plurality of wireless access points are centrally controlled by a controller may be employed.

In the communication system 10 shown in FIG. 7, instead of AP3 ₁ to AP3 ₃ serving as wireless access points, AP30 _{1 to} AP30 ₃ corresponding to control type are adopted, and an AP controller that controls each of these AP30 _{1 to} AP30 ₃ is used. Except for the point that 31 is newly provided, the other configuration is the same as that shown in FIG. The AP controller 31 sets and changes various communication parameters for each of the APs _{30 1 to} AP 30 ₃ , for example, SSID (Service Set Identifier), radio wave intensity, used channel, packet filtering, and the like via the communication line network 2.

In the configuration shown in FIG. 7, the installation positions of the APs _{30 1 to} AP _{30 3} are detected by the GPS receivers 4 ₁ to 4 _3. However, at the stage of constructing the communication system 10, the APs 30 _{1 to} AP _{30 3 are configured.} If the respective installation positions are measured, the GPS receivers 4 ₁ to 4 ₃ can be omitted.

FIG. 8 is a diagram showing a second modification of the communication system 10 according to the present invention made in view of the above points. The communication system 10 shown in FIG. 8 adopts an AP controller 32 in place of the AP controller 31, and other configurations except that the GPS receivers 4 ₁ to 4 ₃ are omitted are shown in FIG. Are the same. The AP controller 32 stores in advance position information indicating the installation positions of the APs _{30 1 to} AP _{30 3} measured in advance as described above. AP controller 32 performs setting and change of the communication parameters for similarly AP30 ₁ ~AP30 ₃ each with the AP controller 31, via the AP30 ₁ ~AP30 ₃ each installation position indicating the position information communication network 2 To the corresponding AP 30 respectively. That is, in the communication system 10 shown in FIG. 8, the APs 30 _{1 to} AP 30 ₃ acquire position information indicating their installation positions from the AP controller 32.

In the communication system 10 described above, three AP3 ₁ to AP3 ₃ are provided as wireless access points. However, one or four or more, that is, at least one wireless access point may be connected to the communication network 2. It is good.
